cant figure out where to start

hi i have the "Starting out with C++" by Tony Gaddis 2nd Ed. and cant find the floppy is there a place u can download whats on it?..........my main problem is with chapter 3, page 151, Programing Challenge #13

its shows this formula

payment = Rate * (1+Rate)^n * L

((1+Rate)^n-1)

and i am asked to make a program that asks for "n" , Rate, and "L" and displays a report simliar to this one

Where; Rate = Interest rate, N=Number of payments, and L=Amount of the loan

Loan Amount: $10000.00

Monthly Interest Rate: 1%

Number of Payments: 36

Monthly Payment: $ 332.24

Amount Paid back: $11957.00

Interest Paid: $ 1957.00

I cant figure out how to write the formula to get what it asks for? any ideas........i was thinking i use "POW"? but cant seem to find in my book anywhere if just gives the above example, since this is for class i dont want a complete answer......just alittle help figuring out how to use the formula.

thanks :cool:
